Description

Technical Field

[0001] The utility model belongs to the technical field of drainage, in particular to a transformer substation and a rainwater drainage collection system. Background Art

[0002] Substations are the connection points of power transmission and distribution systems, responsible for the transmission, conversion, distribution, and control of electrical energy. Rainwater collection systems collect rainwater based on demand and process it to meet design standards, or they can be directly discharged through drainage systems. Most systems consist of a wastewater filtration system, a water storage system, or a drainage system. Currently, substation rainwater is directly discharged through either scattered drainage (unorganized drainage) or a rainwater pipe network system (organized drainage).

[0003] Scattered drainage, also known as unorganized drainage, refers to a drainage method that directly drains the accumulated water in the booster station site to the station road through the site slope, and then drains the accumulated water to the gate or wall through the station road and then out of the substation. This method has the advantages of simple structure and low cost, but has the following disadvantages: (1) When collecting and discharging rainwater, scattered drainage has poor drainage capacity. In rainy areas, it is easy to form water accumulation, affecting drainage efficiency; therefore, scattered drainage is only suitable for areas with little rainfall; (2) After the rainwater is discharged from the gate, the drainage pressure of the drainage system of the road outside the station is increased; (3) After the water is discharged through the drainage holes on the wall, it is easy to affect the surrounding environment such as farmland greening.

[0004] The rainwater pipe network system, also known as organized drainage, is a system that lays pipes and digs wells within the substation, and separates rainwater and sewage. Rainwater is discharged into the nearby urban rainwater pipe network outside the station through the rainwater wells; domestic sewage is treated in septic tanks and then transported away, and is not discharged outside. There are the following shortcomings: (1) The use of organized drainage requires the installation of water collection wells, drainage pipelines, pumps, and foundations. It is necessary to dig open channels, bury pipes, and dig wells in multiple locations within the substation, which makes on-site construction cumbersome and expensive. (2) The substation collects rainwater and directly connects it to the municipal pipe network or discharges it into the nearest river without treatment. If the substation is built in a remote area and is far away from the nearby municipal pipe network, construction is inconvenient and economical. If it is discharged into the nearby river, it is easy to pollute the ecological environment. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a substation and rainwater drainage collection system, which can realize the collection and utilization of rainwater.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions:

[0007] The utility model firstly proposes a rainwater drainage collection system, which includes a perforated curbstone arranged between the road and the electrical area and an underground water storage tank buried in the electrical area;

[0008] The electrical area is provided with a gravel floor for filtering and purifying rainwater and a water-proof clay layer for diverting rainwater to the buried water tank;

[0009] The perforated curbstones are provided with through holes connecting the road and the electrical area at intervals; the road is sloped toward the perforated curbstones so as to divert rainwater through the perforated curbstones to the electrical area.

[0010] Furthermore, the gravel floor includes a gravel surface layer, a sand and gravel layer, a fine sand layer and a coarse stone layer arranged in sequence from top to bottom. The water-repellent clay layer slopes toward the buried water tank and collects the clean water filtered by the gravel floor into the buried water tank.

[0011] Furthermore, the underground water tank is provided with a ventilation pipe extending above the ground of the electrical area.

[0015] Furthermore, the distance between two adjacent through holes is 10 to 15 cm, and the inner diameter of the through hole is set to 8 to 12 cm.

[0016] The present utility model also proposes a substation, comprising a living area, a service area and a production area, wherein the production area is provided with the rainwater drainage collection system as described above; the living area and the service area are both provided with hardened floors and green areas; the hardened floor is sloped toward the road and drains rainwater to the road.

[0017] Furthermore, a domestic water storage tank is provided in the living area, and a water inlet pipe is provided on the domestic water storage tank for pumping clean water in the buried water storage tank into the domestic water storage tank.

[0018] Furthermore, the slope of the road toward the perforated curb is 0.3%-6%; the slope of the hardened floor toward the road is 0.3%-6%; the slope of the waterproof clay layer toward the buried water tank is 0.3%-6%.

[0019] The beneficial effects of the present invention are:

[0023] (2) The problem of water discharge from existing drainage sites to roads was solved by installing perforated curbstones;

[0024] (3) Compared with the organized drainage of existing substations, this system not only improves drainage efficiency and avoids water accumulation, but also eliminates the need to set up water collection wells, drainage pipelines, water pumps and foundations. Instead, it only requires setting up gravel floors and burying underground water storage tanks in the electrical area, which reduces construction costs, improves economy, and is convenient and practical.

[0025] (4) Compared with the organized drainage of existing substations, it avoids the need to dig open ditches and wells when arranging the rainwater pipe network system, effectively saving land, improving the land utilization rate of the substation, and saving land costs;

[0026] (5) Rainwater can be filtered and used for daily production and life in the substation, which not only saves water resources but also effectively solves the problem of the impact of rainwater discharge on the surrounding environment and the high cost of discharge to the municipal pipeline network.

DETAILED DESCRIPTION

[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0034] like Figure 1 As shown, the substation yard of this embodiment includes a living area 10, a service area 20, and a production area 30. The living area is provided with a first hardened floor 11 and a first green area 12, the service area 20 is provided with a second hardened floor 21 and a second green area 22, and the production area 30 is provided with a road 31 and an electrical area 32. In this embodiment, the production area 30 is also provided with a rainwater drainage system.

[0035] Specifically, the rainwater drainage collection system of this embodiment includes a perforated curbstone 33 arranged between the road 31 and the electrical area 32 and an underground water tank 34 buried in the electrical area 32. The electrical area 32 is provided with a crushed stone floor 35 for filtering and purifying rainwater and a waterproof clay layer 36 for draining rainwater to the underground water tank 34. The perforated curbstone 33 is provided with through holes 331 connecting the road 31 and the electrical area 32 at intervals. The road 31 is sloped toward the perforated curbstone 33 to drain rainwater through the perforated curbstone 33 to the electrical area 32. Specifically, the first hardened floor 11 and the second hardened floor 21 are both sloped toward the road 31 and drain rainwater to the road 31.

[0036] Thus, the substation of this embodiment installs a perforated curb 33 between the road 31 and the electrical area 32. The road 31 is sloped toward the perforated curb 33, allowing rainwater to flow through the road 31 to the perforated curb 33 and into the electrical area 32 through the through-holes 331 provided in the perforated curb 33. The gravel floor 35 within the electrical area 32 filters and purifies the rainwater, which is then channeled into the underground water storage tank 34 using a water-repellent clay layer 36. This filtered rainwater is then filtered, purified, and collected for reuse as water for production and daily life.

[0037] Specifically, to achieve the technical purpose of filtering and purifying rainwater, the gravel floor 35 of this embodiment includes a gravel surface layer 351, a sand and gravel layer 352, a fine sand layer 353, and a coarse stone layer 354, arranged sequentially from top to bottom. A water-blocking clay layer 36 is provided beneath the gravel floor 35. Specifically, in this embodiment, the water-blocking clay layer 36 slopes toward the underground water tank 34 and collects the purified water filtered by the gravel floor 35 into the underground water tank 34. Thus, utilizing the gravel floor 35 and water-blocking clay layer 36 laid within the electrical area 32, rainwater can be filtered, purified, and drained, ultimately collecting the resulting purified water into the underground water tank 34. The collected rainwater does not need to be discharged externally, thus solving the problem of rainwater discharge. Furthermore, the cost is lower than that of organized drainage, and the rainwater treatment efficiency is higher than that of unorganized drainage.

[0038] In a preferred embodiment of this embodiment, the underground water tank 34 is provided with a ventilation pipe 341 extending above the ground of the electrical area 32. A manhole 342 is also provided on the underground water tank 34 to facilitate inspection and maintenance of the underground water tank 34. An outlet pipe 343 is also provided on the underground water tank 34 to facilitate extraction of clean water stored in the underground water tank 34. Specifically, a domestic water tank 13 is provided within the living area 10, and the domestic water tank is provided with an inlet pipe for pumping clean water from the underground water tank 34 to the domestic water tank 13. Thus, the clean water in the underground water tank 34 can be pumped to the domestic water tank 13 via the outlet pipe 343 and the inlet pipe provided on the underground water tank 34.

[0039] In this embodiment, a cement mortar base 332 is placed beneath the perforated curbstone 33. The side of the perforated curbstone 33 that contacts the road 31 is coated with asphalt to prevent rainwater from seeping directly into the gravel floor 35. Specifically, the spacing between adjacent through-holes 331 is 10-15 cm, and the inner diameter of each through-hole 331 is 8-12 cm. In this embodiment, the spacing between adjacent through-holes 331 is 12 cm, and the inner diameter of each through-hole 331 is 10 cm.

[0040] Specifically, to ensure smooth rainwater collection, the slope within the substation should be no less than 3‰ and no greater than 6%. That is, in this embodiment, the road 31 is flat, and the slope of the road 31 toward the perforated curb is 0.3%-6%. The slope of the first hardened floor 11 and the second hardened floor 21 toward the road 31 is 0.3%-6%. The slope of the water-blocking clay layer 36 toward the buried water tank 34 is 0.3%-6%. Specifically, in this embodiment, the slope of the road 31 toward the perforated curb is 1%. The slope of the first hardened floor 11 and the second hardened floor 21 toward the road 31 is 3%. The slope of the water-blocking clay layer 36 toward the buried water tank 34 is 0.5%.

[0041] The above-described embodiments are merely preferred embodiments for the purpose of fully illustrating the present invention, and the scope of protection of the present invention is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present invention are within the scope of protection of the present invention. The scope of protection of the present invention shall be subject to the claims.
